1 / 63 page ST Sitronix ST7586S 4-Level Gray Scale Dot Matrix LCD Controller/Driver Ver-1.1a 1/63 2009/11/30 INTRODUCTION ST7586S is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems. It contains 384-segment and 160-common driver circuits. This chip can be connected directly to a microprocessor which accepts 8-bit parallel interface (8080-series or 6800-series type), 4-Line serial interface or 3-Line serial interface. Display data is stored into an on-chip Display Data RAM (DDRAM). It performs the Display Data RAM read/write operation without external operating clock, and the power consumption can be minimized. In addition, since all necessary power supply circuits for LCD system are built-in, ST7586S constructs a LCD display system with the fewest components. FEATURES Single-chip LCD controller/driver Driver Output Circuits ♦ 384 segment outputs / 160 common outputs On-chip Display Data RAM ♦ Capacity: 384 x 160 x 2 = 122,880 bits Various Partial Display Features ♦ Applicable partial duty ♦ Partial window moving & data scrolling Microprocessor Interface ♦ 8-bit parallel bi-directional interface supports 6800-series or 8080-series MPU ♦ 4-Line serial interface ♦ 3-Line (9-bit) serial interface On-chip Low Power Analog Circuit ♦ On-chip oscillator circuit ♦ Voltage booster with built-in boost-capacitors ♦ Extremely few external components: 4 capacitors ♦ Built-in voltage regulator with programmable contrast ♦ Built-in voltage follower supports LCD bias voltage Available bias: 1/9 ~ 1/14 Operating Voltage Range ♦ Digital Power (VDD1): 1.8V ~ 3.3V (TYP.) ♦ Analog Power (VDD2~VDD5, VDDX): 2.8V ~ 3.3V (TYP.) ♦ LCD operation voltage (Vop = V0-XV0) : 18V Built-in OTP−ROM for LCD Vop Optimization Package Type: COG ST7586S 6800, 8080, 4-Line & 3-Line Interface Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice. |
